Introduction: Intra-hospital infections (IIH) by antibiotic-resistant bacteria is a public health problem for governments, due to the fact that hospital infrastructure constitutes a favorable reservoir for various pathogens, without having art-based pathogen control solutions. not antibiotics. For this reason, antibacterial applications of biomedical textiles that include copper wire for the use of health personnel and patients emerge as a sanitary and effective option to control the growth and spread of these pathogens. Objective: To evaluate the bactericidal activity of copper wire against the main pathogens that cause IIH resistant to carbapenemases E. coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Staphylococcus aureus. Design: Experimental study with non-probabilistic sampling. Materials and Methods: 4 bacterial strains resistant to carbapenemases; E. coli, P. aeruginosa, K. pneumoniae and S. aureus; biomedical textile with copper wire (1cm2) and textile without copper (control-1cm2). Interventions: 4 bacterial strains were provided by UPAO. The analysis by means of ANOVA and Tukey (p<0.05), were applied to evaluate the bactericidal capacity of the biomedical textile with copper thread and textile without copper against the 4 strains that cause IIH, through the use of statistical programs, Microsof Excell RealStatistis respectively. There are differences in the growth of bacteria in textiles with copper wire compared to textiles without copper wire, with respect to exposure time (180min). Results: K. pneumoniae, P. aeruginosa, E. coli and S. aureus strains exposed to copper biomedical textile were killed in 80, 90, 120 and 140 minutes, respectively. The bacterial load of the cells (~1x105 CFU/mL) exposed in textile without copper wire remained constant and viable for periods longer than 180 minutes. In addition, the copper wire killed Gram-negative bacteria (K.pneumoniae, P. aeruginosa, E. coli) faster than Gram-positive bacteria (S. aureus). Conclusions: Biomedical textile with copper wire completely eliminates nosocomial bacteria such as E. coli, P. aeruginosa, K. pneumoniae, and S. aureus, unlike textiles that lack copper, in which they remain viable. According to our results, copper wire can be applied in biomedical clothing or dressings to prevent or treat infections caused by carbapenemase-resistant intrahospital pathogens
